DETAILED DESCRIPTION

Hereinafter, various embodiments of the present disclosure will be described with reference to various embodiments of the present disclosure. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

In the present disclosure, the expression “have”, “may have”, “include” or “may include” refers to existence of a corresponding feature (e.g., numerical value, function, operation, or components such as elements), and does not exclude existence of additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used herein are merely for the purpose of describing particular embodiments and are not intended to limit the scope of other embodiments. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

FIG. 1 is a perspective view illustrating a conventional foldable electronic device. Referring to FIG. 1, a conventional foldable electronic device 10 may be implemented as a foldable portable terminal, and may include a display 11 that is concealed from the outside in the folded state. The display 11 may display an image. In the state where the electronic device is folded, the display 11 may be concealed by the electronic device 10.

The electronic device 10 may be provided with a cover 12 that is formed of a flexible material, such as a leather material or a rubber material, so that the sense of an exterior design can be diversified. The electronic device 10 may be configured to be foldable so that the electronic device 10 can be conveniently carried.

However, in order to use the electronic device 10, it is necessary to unfold the electronic device 10, which may be troublesome and inconvenient. Thus, the teachings of invention addresses the drawbacks of conventional foldable device, as explained hereinafter.

FIG. 2 is a perspective view illustrating an electronic device according to a first one of various embodiments of the present disclosure. FIG. 3 is a cross-sectional view illustrating the electronic device according to the first one of various embodiments of the present disclosure. FIG. 4 is a rear view illustrating the electronic device according to the first one of various embodiments of the present disclosure. FIG. 5 is a cross-sectional view illustrating the electronic device according to the first one of various embodiments of the present disclosure in the folded state.

Referring to FIGS. 2 to 5, according to one of various embodiments of the present disclosure, an electronic device 100 may include a first display device 101, a cover 103, and a second display device 105. Here, the electronic device 100 may be a portable terminal. However, the electronic device 100 may be any of various electronic devices that include a foldable display (e.g., a flexible display device) without being limited to the portable terminal.

The first display device 101 may include a body 113 and a flexible display device 111, and may be an image displaying device that is configured to be foldable. The body 113 may include a circuit unit (e.g., a circuit board) that processes communication, various pieces of information, or the like, a battery that supplies power, etc. The body 113 may be folded or unfolded. The flexible display device 111 is provided on the front face of the body 113, and may be folded or unfolded together with the body 113. The flexible display device 111 may output an image under a control of the circuit board included in the body 113, or the like. For example, the first display device 101 may include the flexible display device 111 so as to operate as an image displaying device.

The cover 103 is provided on the rear face of the body 113 to be foldable together with the body 113. The cover 103 may be formed of a flexible material, such as a leather material or a rubber material. However, the material of the cover 103 is not limited to the flexible material. A portion, which is deformed in a curved shape at a folding operation, of the cover 103 may be formed of a flexible material, and the cover 103 may also include a portion, which is capable of maintaining a predetermined shape regardless of the folding operation and that is formed of a rigid material, such as, for example, a plastic or a metal. Accordingly, a portion of the cover 103, which is capable of maintaining a predetermined shape even at the folding operation, may be provided with components that are required for the electronic device, such as a circuit unit (e.g., an antenna radiator).

The second display device 105 may be disposed, for example, on the rear face of the body 113 to be opposite to the flexible display device 111. As illustrated in FIGS. 3 and 4, the second display device 105 may be concealed by the cover 103 in the state where the body 113 is unfolded. In addition, when the body 113 is folded, for example, when two different portions of the body 113 are folded in the direction where the two different portions face each other, a portion of the rear face of the body 113 may be exposed depending on the thickness of the electronic device 100 and the curvature in the folded state, as compared to the state where the body 113 is unfolded. For example, as illustrated in FIGS. 2 and 5, the second display device 105 may be exposed to the outside of the cover 103 in the state where the body 113 is folded. This is caused due to a difference in relative displacement between the first display device 111 and the cover 103 at the folding operation. The first display device 111 and the cover 103 may be coupled to be at least partially slidable in relation to each other.

As the second display device 105 is exposed in the state where the electronic device is folded, various pieces of information, such as weather information, time, phone call reception, and text message reception, may be output through the second display device 105. Accordingly, the user may use the electronic device 100 while confirming various pieces of information through the second display device 105 even in the state where the flexible display device 111 is folded.

In addition, when a touch screen function is incorporated into the second display device 105, a displayed icon may be changed or an operation mode of the electronic device may be changed according to the user's touch input.

Referring to FIG. 5, while one end of the body 113 and one end of the cover 103 are fixed to each other at a first fixing portion 107, the cover 103 may be coupled to the body 113 to be at least partially slidable. Accordingly, when the electronic device 100 is folded, the other end of the cover 103 may move toward the central portion of the cover 103 such that a portion of the rear surface of the body 113 can be exposed. By arranging the second display device 105 in the region that is exposed according to the movement of the cover 103, the second display device 105 may be exposed to the outside of the cover 103 as the first cover 103 is slid.

FIG. 6 is a perspective view illustrating the electronic device according to first one of various embodiments of the present disclosure in the folded state. FIG. 7 is a illustrating a joint portion of FIG. 6 in an unfolded state.

Referring to FIGS. 6 and 7, according to the first one of various embodiments of the present disclosure, the electronic device may include a plurality of joints 109. Each of the joints 109 may include a first facing portion 191, a second facing portion 193, and inclined portions 195. The first facing portion 191 may face the first display device 101. The second facing portion 193 may have a length that is shorter than that of the first facing portion 191, and may face the cover 103. The inclined portions 195 interconnect the opposite ends of the first facing portion 191 to the opposite ends of the second facing portion 193, respectively, and may be inclined relative to the first facing portion 191. Even if the first display device 101 are folded in the direction in which the two different regions face each other, the plurality of joints 109 are placed in the state where the entire length of the surface, on which the first facing portions 191 are arranged, may be maintained to be the same as the unfolded state. For example, at the folding or unfolding operation, the joints 109 may stably support the first display device 101 while causing the first display device 101 to be deformed at a proper curvature. On the contrary, at the folding operation, in the portion that is deformed in a curved shape, the length of the cover 103, which is arranged on the second facing portions 193 may be changed by the change in distance between the second facing portions 193. The change in the length of the cover 103 in the portion that is deformed in the curved shape may move the other end of the cover 103 toward the central portion of the cover 103.

As described above, according to the first one of various embodiments of the present disclosure, since the electronic device 100 includes a plurality of joints 109 that face each of the first display device 101 and the cover 103, at least a portion of the cover 103 may be relatively moved in relation to the first display device 101 in the state where the body 113 and the cover 103 are folded.

FIG. 8 is a view illustrating a relationship between a region in which the second display is exposed and a cover, which are applied to the electronic device according to the first one of various embodiments of the present disclosure. First, with reference to

FIG. 8, a center line “L”, a radius “R”, a thickness “t”, a slope “a”, and a displacement “d” are defined. The center line “L” may be a virtual line that interconnects the center and the contact point of the opposite ends of the folded first display device 101. The radius “R” may refer to a curvature radius of a curved portion that is formed as the first display device 101 is folded. The thickness “t” may refer to the thickness of the cover 103. The slope α may indicate an inclined angle of the first display device 101 in relation to the center line “L”. The displacement “d” may refer to the displacement of the other end of the cover 103 in relation to the first display device 101.

As illustrated in FIG. 8, as the first display device 101 is folded, the cover 103 may be positioned at a radius (“R”+“t”) that is larger than the radius R of the first display device 101. When the lengths of the cover 103 and the first display device 101 are practically unchanged in the portion that is deformed in the curved shape, the cover 103, which has the larger radius at the other end of the first display device 101, may move relative to the first display device 101 in the process of being folded or unfolded. For example, as the thickness t of the cover 103 increases, the relative movement of the cover 103 with respect to the first display device 101 may further increase. Accordingly, the second display device 105 may be set to correspond to the displacement “d” that corresponds to the distance that the of the cover 103 moves relative to the first display device 101. That is, the second display device 105 may be set to correspond to the displacement that is proportional to the thickness “t” of the cover 103. For example, the size of the second display device 105 may be set to correspond to the displacement that is proportional to the thickness t of the cover 103.

In addition, the relative movement of the cover 103 is variable depending on the slope α. For example, when the slope a increases, the radius R of the first display device 101 may also increase, which may increase the relative movement of the cover 103 with respect to the first display device 101.

FIG. 9 is a view illustrating a guide that is applied to the electronic device according to the first one of various embodiments of the present disclosure. FIG. 10 is a cross-sectional view illustrating a first guide and a first guide hole, which are applied to the electronic device according to the first one of various embodiments of the present disclosure.

Referring to FIGS. 9 and 10, according to the first one of various embodiments of the present disclosure, the cover 103, which is applied to the electronic device 100, may include a first guide 131, and the body 113 may include a first guide hole 115.

The first guide 131 may be formed to extend from the lower portion of the cover 103 and to protrude toward the body 113. The first guide 131 may be formed in the longitudinal direction of the cover 103, for example, along a direction in which the cover 103 moves relative to the body 113. The first guide hole 115 is provided in the body 113, and may be formed to correspond to the first guide 131. In addition, the first guide 131 may be slid along the first guide hole 115 while being restrained by the first guide hole 115.

In this way, according to the first one of various embodiments of the present disclosure, in the electronic device 100, as the first guide 131 is slid while being restrained by the first guide hole 115, the cover 103 may correspondingly move relative to the body 113 without being released from the body 113.

FIG. 11 is a cross-sectional view illustrating an electronic device according to a second one of various embodiments of the present disclosure in a folded state.

Referring to FIG. 11, according to the second one of various embodiments of the present disclosure, because the first display device 201, the cover 203, and the second display device 205 of the electronic device 200 are similar to those of the above-described embodiment, detailed descriptions thereof will be omitted.

According to the second one of various embodiments of the present disclosure, the electronic device 200 may include a first region F1 and a second region F2. The first region F1 may refer to a region that is deformed in a curved shape in the state where the electronic device 200 is folded. The second region F2 may refer to two regions that face each other in the state where the electronic device 200 are folded.

The first display device 201 may include a body 213 and a flexible display device 211, and may be an image displaying device that is configured to be foldable. The body 213 of the first display device 201 and the cover 205 may be fixed to a second fixing portion 207 at a side of the portion in which the first region F1 and the second region F2 are connected to each other. One side of the body 213 and one side of the cover 203 that are fixed to the second fixing portion 207 may be fixed without being affected by the relative movements of the body 213 and the cover 203 in the first region F1. The other side of the cover 203 may be moved toward the first region F1 by the relative movements of the body 213 and the cover 203 in the first region F1. Accordingly, the second display device 205 may be exposed to the outside of the cover 203.

FIG. 12 is a cross-sectional view illustrating an electronic device according to a third one of various embodiments of the present disclosure. FIG. 13 is a rear view illustrating the electronic device according to the third one of various embodiments of the present disclosure. FIG. 14 is a cross-sectional view illustrating the electronic device according to the third one of various embodiments of the present disclosure in the folded state.

Referring to FIGS. 12 to 14, according to the third one of various embodiments of the present disclosure, because the first display device 301, the cover 303, the second display devices 305 and 307 of the electronic device 300 are the same as those of the above-described embodiments, detailed descriptions thereof will be omitted.

The body 313 of the first display device 301 and the cover 303 may be fixed to each other at a third fixing portion 309 where the central portion of the body 313 and the central portion of the cover 303 are in contact with each other. In addition, when the body 313 and the cover 303 are folded, the opposite ends of the cover 303 may be slid on the body 313 toward the third fixing portion 309 as in the preceding embodiments.

In addition, the second display devices 305 and 307 may be provided on the opposite ends of the body 313, respectively. The second display devices 305 and 307 may be exposed to the outside or exterior area of the cover 303 as the opposite ends of the cover 303 are slid.

In addition, the body 313 may be provided with sensors 317 a and 317 b that sense the sliding extents of the opposite ends of the cover 303 along the rear face of the body 313. The sensors 317 a and 317 b may be optical sensors that sense the movements of the opposite ends of the cover 303 or may be configured to be in physical contact with the cover 303 to sense the opposite ends of the cover 303. The sensors 317 a and 317 b may include first sensors 317 a that are arranged to be spaced apart from one 305 of the second display devices and second sensors 317 b that are arranged to spaced apart from the other 307 of the second display devices. The first sensors 317 a and the second sensors 317 b may be arranged to be symmetrical with each other with reference to the third fixing portion 309. For example, the first sensors 317 a and the second sensors 317 b may be oppositely oriented to each other when the body 313 and the cover 303 are folded. The first sensors 317 a may sense the outwardly exposed extent of one 305 of the second display devices, and the second sensors 317 b may sense the outwardly exposed extent of the other 307 of the second display devices. That is, the first and second sensors 317 a and 317 b may sense the outwardly exposed extents of the second display devices 305 and 307, respectively, and may transmit sensing signals to a processor of the electronic device, and the processor may calculate each of the outwardly exposed areas of the second display devices 305 and 307. In addition, the processor may calculate the folded degree of the flexible display device 311 (e.g., a relative angle between one portion of the body 313, on which one 305 of the second display devices is provided, and the other portion of the body 313, on which the other 307 of the second display devices is provided) based on the sensing signals. In addition, the third one of various embodiments of the present disclosure exemplifies a configuration in which the sensors 317 a and 317 b are arranged on the body 313. However, the sensors 317 a and 317 b may be arranged on the cover 303 rather than on the body 313, and may be electrically connected with a circuit unit within the body 313.
